End Gcode For Rostock MAX in Cura 13.11.2

[bill-havins 0]

Hello to All,

I am considering using Cura 13.11.2 as the "preferred" slicer for my Rostock MAX. This most recent version of Cura has some very attractive features and seems to work very well. Bravo!

I am having difficulty developing end gcode that works reliably. The "postfix" I am presently using works pretty well, but, after the "G28" is issued (see below) the axes do home, but then begin to step backward very, very slowly. This includes the extruder. The only way I can stop this backward stepping is by turning the printer power off.

M104 S0

M140 S0 ; bed heater off

G92 E0 ; set extruder position to zero

G28 ; home X, Y, and Z axes

M84 ; disable stepper motors

I would appreciate suggestions for developing better end gcode.

Thanks!

Bill

Do you need to simply remove the M84, so that the motors remain powered, and hence locked in place?

Thanks for the response. I'll give that a try. I "think" I have already tried the end gcode without the "M84" and got similar behavior. I'll report back later today.

Thanks again!

Deleting the "M84" command has no effect on the reported problem. I'm not sure what to try next.

Try doing only a home, then an M84 gcode. After that are the steppers on? Can you move the print head? Or are the servos still on?

Slice with some other slicer that works for you - then look at the gcodes towards the end.

Here is an end gcode routine that works well in Slic3r and KISSlicer. I wonder if the problem is a firmware issue?

G92 E0; zero extruder

G91; incremental mode

G1 Z3 E-8 F5000; raise Z and reverse filament

G90; absolute mode

G28 ; home axes

M104 S0 ; turn off temperature

M140 S0

The above just doesn't seem to work with Cura. Disappointing.

What 'doesn't work with Cura' about it? Cura doesn't care either way, really. The end gcode is jsut text that gets appended to the file, and sent to the printer.

There's nothing non-standard about either version of the end gcode - they both do much the same thing, and using very standard Marlin gcodes. The only difference is that the one that 'works' doesn't explicitly turn the steppers off.

upload the gcode generated by cura gcode or your cura profile to check it

The CURA endcoade for Rostock machines needs to be improved. I have, on multiple occasions, ruined freshly printed parts by forgetting to change the endcode.

All you need is a G28 command - that will home the machine. I am running a RostockMAX and it works fine. Here is the endcode i use, i strip out anything that is not required to keep it simple.

M104 S0

M140 S0

G28

M84

This works fine, i do not get the motor creep' you speak of.

Hope this helps, would love to see CURA improved for the Rostock machines in the future.

What firmware are you running? Some older versions of Repetier fw for Deltas could not handle Curas profile string at the end and this same behaviour occured. Try deleting that last line..

Thanks, gadgetfreak. Deleting the configuration string (the last line of the gcode) solved the problem.

I am now using Cura 14.01 for all slicing tasks and it is performing well. I really appreciate the efficiency of motion it produces (few-to-no unnecessary hotend movements).

I have successfully converted my Rostock MAX to a dual extruder configuration and Cura slices models such that they print very well.

It would be nice to have the option to "turn off" inclusion of the configuration line in the gcode. But, hey, if that's the only problems I have with Cura it's no big deal.

Next week I'll begin printing files using HIPS for support material. I hope things continue to work well.

Thank you, Daid, et al. This is a great slicer.
